Patented Oct. 23, 1945 Y rec stares rarely Earl W. Gardner and William F. Nickum, Salt Lake City, Utah, assignors to Remington Arms Company, Inc., Bridgeport, Conn., a corporation of Delaware Application December 27, 1943, Serial No. 515,656 1 Claim. (01. 198-441) This invention relates to ammunition making machinery and particularly to a means for conveying elements, such as primer components, or primer assemblies. nents of primers such as the cups, it is desirable to handle with care so as to prevent injury. The

elements are small and easily scattered so that the conveyor system should be one which handles the articles carefully and confines them to prevent In the handling of compothe belt. The primers are shown diagrammatically at 42 in the lowermost pocket 4|. As the belt revolves in the direction shown by the arrow in Fig. 1, the primer receiving pockets are carried upwardly to the position shown at 3| and up to 43. At the point shown at 43, the primers in the pocket slide around the smooth interior wall of the pocket ready to drop out onto chute 44. Chute 44 directs the primers from the machine in any loss and scattering. As an example, the primer l.) desired direction. The shape of the pockets is cup of a caliber .30 cartridge is about 0.2" in dimade such that the cups will slide smoothly on ameter and 0.12"- high. These and other objects the surface thereof and will drop' therefrom into of the invention will become apparent from the the chute 44 without any undue accelerated mofollowing drawings and description which are tion. The form of pocket shown in Fig. 4 commerely exemplary of the invention. prises two radii and straight surfaces, although In the drawings: it is evident that other geometrical surfaces may Fig. 1 is a vertical elevation partially in section be selected to give the desired smooth action withand broken in the center of a conveyor embodyout abrupt dropping. It is desirable that there be ing the invention, the lower half being in section an enlarged chamber 50 remote from the opening and the upper half a side view looking from the 5| of the poc and t a the Chamber e joined left of Fig. 2. by a smooth or gradually curving surface 52 there- Fig. 2 is a side view of Fig. l and is partly in with. section. In this manner, primers will fall into the pocket Fig. 3 is a top View of Fig. 1. when the pocket is in the lowermost position. The Fig. 4 is a detailed side view of one of the primer cups will then move toward the enlarged chamconveyor pockets. ber 50 as the pocket is carried upwardly by the Fig. 5 is a schematic elevation of the conveyor belt. When the pocket is carried around the as employed with a primer shaker machine, upper Se O p l ys, t e primers will gradually Referring to the drawings, belt 20 may be made slide along t e Sur e 52 t the Opening 5| and of leather or any other suitable material. .The fall into the discharge chute. belt is carried between the lower set of pulleys at The flanges 53 of the pockets may e fastened 2| and the upper set at 22. The pulleys are 110 the belt 20 y rivets y y Suitable mounted on shafts 23 and 24. The lower set of means, ther being penings 55 cut in the belt pulleys 2| comprise two pulleys 25 and 26, which as indicated, have a flange 2! and 28, said flanges serving to One use of the machine is seen in Fig. 5 whereguide the belt 20. The upper set of pulleys is in a primer shaker plate machine is shown diasimilar to the lower set and comprises two pulleys r mm i ally at 45. This machine is.described 29 and 30. in detail in a copending application Serial Num- The primer or article receiving pockets are inher 514,390 filed December 15, 1943. The primers dicated at 3|, details thereof being shown in Fig. are d into the hop p 46 a d ar shaken 4. The shaft 23 may be adjustably supported on nto a primer plate thereunder. The excess posts 32 and 33, said posts carrying the journals primers fall into the bin 41 and are carried by 34 and 35. Either shaft 23 or 24 may be driven by m ans f the ute 36 nto t e conv yor of the a pulley by a suitable means of power not shown present inVentiOIle Conveyor 0f the p t in order to rotate the belt to elevate articles from invention then raises the primers and delivers alower position to an upper position In the form them to the chute 44 which returns the excess shown, the driving pulley is indicated at 53. primer cups to the p r The el p y The primers, or other objects, are directed to a d other p r s ar m re s shown in dia rammathe interior of the conveyor through chute 36, tie f m in Fig. as their construction is found which enters the interior chamber through a hole 50 n deta i t e other figures of the drawings.

Guide plates 39 and 40 serve to direct the cups away from the pulleys and into the primer receiving pockets, one of said pockets being shown at 4| at the bottom point of travel of It is apparent that other articles than. primer cups may be handled by the present invention, the device being particularly adaptable for handling small objects without damage, although it is to be understood that it is not limited thereto.

What is claimed is:

In a device for vertically elevating loose articles, an upper arbor; a lower arbori a, pair of spaced counterpart pulleys secured to each of said arbors, each pulleys of each pair comprising a, flange adapted for engagement with one edge of a belt; a continuous belt of strip materia1 extending between and passing around said pairs of pulleys, there being spaced apertures in said belt; article receiving pockets secured to the margins of said 10 apertures and extending outwardly therefrom,

said pockets being transversely enlarged from their mouth portions at said belt apertures and laterally asymmetric to afiord a support for articles therein during the vertical upward movenment thereof; means for introducing articles into said pockets between said lower pair of spaced pulleys; and means for receiving articles delivered from said pockets between' said upper pair of spaced pulleys.
